' 'f "we, and :Wlan the howex'ex' fxe arms s he and face of '5311s the im posmon shown in l in i, speiylg 23. ""he s e] wm-@dy so as to have a downpor'ion' 2G which is .A 1in-nl 271" of winng of ch dement 24 is @hen has a dcwnr wardly extending portion 28 which lies in eoutact with a conducting plate Q9 carrying at its tree extremity a connector 30. Another terminal ot the winding is connected to a downwardly projecting apron 3l ot ar forwardly extending conducting plate 3i). which has electrical contact with the conducting bar 33 carrying at its tree end a connector Si. A third conductor 35 leads .from the winding and is soldered to a rearwardly extending Contact clip 3G carried by the conducting plate 37. which conducting plate rests against the lol-shaped element lto thereby secure what might be a ground connection. The explanation just given has set torth how the various conducting elennnts are mounted one above the other. lt may be stated that all ot those elements mounted one above the' other which it is not specifically stated are not in contact. are insulated trom each other and likewise insulated `trom the mounting screws 3S which hold these elements all in place. The armature 6 carries a ba .lwaidly projecting arm 73 which is accommodated for by Va slot r'flin the keeper 4.- and this arm carries an insulating stop 75. lWhen the armature is retracted. shown in Fig. this stop engages the spring llland holds it against its own spring action in the position show n in Fig. 3. il'l'lhen the switch element 'l5 ol" tliisspring, however. engages the contact spring 2', then in its further movement'of the armature as the inclined .faces ot these two springs slide over each other, the spring action ot the spring lflis exerted against the sprinf Q5. the. arms 73 and button 75 continue in their movement to the position shown in Fig. l where the button 75 is outot engagement with the spring i4.

l'elerring more particularlvto Figs. Tte l2 inclusive l show anolhe.` Vform which my improved indicating relay may take7 in which the coil structure 3S is secured to a` keeper 40 oiC magnetic material substantially l-slmpecl, by means ot nuts' a1-i, which nuts at the same time hold a mounting pla-te 4:2. rThe, mountii'ig plate may be secured within a suitable eomjnirtment consisting ot' the base plate 43 and the cover del. which cover has a window 45 vthrough which the target 46 ot. my relay may make its indications. rlhe keeper 40 carries an armature 47 pivotally mounted at 18, to which armature isiixedly secured a projection 49 which in cooperation with a helical spring 5() causes a retraction ot the armature to the position, occupied in Fig. 7. rIhe opposite extremity of the helical spring 50 is mounted in a stud 5l Aforming part of a conducting plate :'32, which conducting plate has a downwardly extending arm to which is soldered one of the conductors 5ft leading from the winding structure 3S. The target 46 Iis pivotally mounted at 55 and las an arm 5G to limit its downward movement. rihe target also has at its opposite extremity a prong 57 .which in combination with the projection 9. a shown more clearly in Fig. 8, serves to limit the upward movement of the target. '.lhe arm .3G also serves another purpose, and that is the actuating of the target, and this is done by a non-magnetic projection 58 which is fastened in the core of the winding structure. New. whenever the armature si? is attracted (Fig. 7), that is, when its right hand extremity moves downwardly. then the pin 58 remaining Ystationanv7 the target t6 will be forced upwardly as shown in Fig. 8. The armature 47 carries a contact element 59 shown more clearly in Fig. 12 which has a pair of curved extendingr arms 60 adapted for contacting purposes with a pair of Contact elements 6l and G2. Contact elements 61 and 62 are held in place by the screws G3, being however insulated from said screws and from the .framework of the relay. The Contact element Gl has a downwardly projecting apron (tl having a slightly curved indentation as shown at G5 to which is soldered a. projecting terminal (5G of the winding. A conducting plate G? carrying a connector 68 is in electrical 'connection with the element (r3 through the agency ot' an upwardly bent sidewise extending portion (59. A'sccond conducting plate 70 is also mounted on the structure by the screw (53 which has a downwardly projecting apron 7l in whose curved recess another terminal of the winding is soldered. New when the armature is in its retracted position, the contact element. 59 is not in engagement with the springs ll and G2 as clearly apparent from Fig. Y, and when the armature is attracted the target moves up into the position oecupied in Fig. 9 as already explained, but at the same time the contact element 59 carrying the lingers G0 nieves upwardly into engagement with the springs G1 and 62, and thereafter is `Further drawn over the snr- 'laees of the elements G1 and 62 into the final position shown in Fig. 8, thus obtaining a rubbing contact between the contacting switch elements.

It is thought from what has been de-` scribed the nature of my invention will loe clear, the two embodiments herein shown illustrating its versatility.

Many modiiications and changes may of course loe made from the structure herein disclosed without departing from the spirit of my invention.

lHaving however thus described two forms which my invention may take, what claim as new and desire to secure oy Letters Patent is:

l. d relay having an electromagnetieelenient, .in armature therefor, a Contact spring, a second contact spring carried by said armature and adapted when said armature is actuated to establish wiping contact with said first aforesaid contact spring, a bridge member secured to said electromagnetic element having a projecting finger carrying a stop for said second'aforesaid contact spring, a retractile spring for said ar- `mature, and a stop-arm forming part of said bridge member With which said retractile spring co-acts.

2. A relay having an electromagneticA element, an armature therefor, a keeper for said electromagnetic element With which said armature coperates, and an indicator pivotally supported upon said armature and coperating with said keeper to occupy different indicating positions.

3. A relay having an electromagnetic element, a core for said element, an armature for said element, a projection provided upon said core, and an indicator pivotally supported upon said armature andco`o`perating with said projection to occupy different indicating positions depending upon the energization or denergization of said element.

4. A relay having an electromagnetic element, an armature for said element, and an indicator pivotally supported upon said armature having means for cooperating with a stationary portion of said electromagnetic element to occupy different indicating positions upon the energization or denergization of said electromagnetic element.

5. A relay having an electromagnetic element, an armature therefor, a spring extended from said armature, an arm carried by said armature and provided with a stop against which said spring impinges, and a second spring with which said first spring is adapted for engagement upon actuation of said armature, the further movement of said armature after engagement of said springs carrying said stop arm away from said first aforesaid spring.

6. A relay having an electromagnetic eiement, an armature therefor, a spring extended iironi said armature, an arm carried by saidarmature and provided with a stop against which said spring impinges, and a second spring with which said first. spring is adapted for engagement upon. actuation of said armature, the further movement of said armature after engagement of said springs carrying said stop arm away from said iii-st aforesaid spring, and a bridge member mounted upon said electromagnetic element and' having a stop for said first aforesaid spring, whereby said stop serves as a back stop for said armature.

7. An indicating relay comprising a U- shaped electromagnetic structure, an armas ture pivotally supported by one of the poles operates with one of said pole pieces to indicate a normal or operated position o1 the armature.
